| Outline of Final Research Achievements |
The envelop of a left-handed (LH) wave moves to the opposite direction to its carrier. This study clarifies how this exotic property affects the resonances of LH waves using CRLH structure.
Owing to the left-handedness, three-wave mixing becomes significant by head-on collisions of short envelope pulses. By the soliton decay in a nonlinear CRLH line, the incident envelope emits several pairs of the fast and slow solitons. It is found that the slow soliton travels backward and the fast soliton becomes shorter for wider incident envelope. Moreover, the generation of second harmonic waves in a nonlinear CRLH line is analyzed on the basis of harmonic resonance.
We introduced field-effect transistors to compensate for decaying waves. Introduction of FETs allows for the line to support either dissipative or stationary soliton that is expected by the reduced Ginzburg-Landau equation and is really observed numerically. We then establish the scheme for managing such solitary waves.
